Fueling Problem ERST S2
Tried to leave this to my tuner to sort out but it he is none the wiser so maybe someone on here can help PLEASE
When I start the car early morning or when its been stood for a long time the fuel pump primes up and i can hear a knocking sound for about 5/7 seconds coming from what seems to be the metering unit or that area. The car will start straight away before the knocking stops but will run rough for about 30 seconds then clear and the car will drive OK. this happened before and after my recent engine rebuild due to the head gasket blowing.
New items that have been changed with engine rebuild or I have done in the last few months
Cam
springs
followers
turbo
all water and oil hoses
injectors serviced/flow tested etc
plugs have now been changed ngkbc8
distributer cap
rotor arm
leads standard ford and a few other bits and bobs but nothing else to do with fuel directly
When i take the plugs out and have a look after 200 miles of driving number 4 is white while the other look brown and fine
I have recently bought a nearly new metering head thats winging its way to me this week hoping that this will cure the problem.
Anybody had anything similar happen or have any ideas at all? this is with and without the cold start valve connected as well

i should think the metering unit should cure it if theres a knocking coming from it cant be good so its proberly fooked, the knocking could be the flap inside, cant think of anything else inside it what moves to produce a knocking sound unless the knocking is in the gearbox or somewhere elsewhere

it sounds like something coming up to pressure, as soon as it reaches it after a few seconds it stops, slight smell of petrol from the engine bay as well, anyone?
